18.2. Tutorial: Light Tube Exchange
As noted at the beginning of this procedure, it is possible to exchange the Light tube without removing
the top of the enclosure. It is highly recommended that you first familiarize yourself with the system by
removing the top cover once so that you are certain of the location of the components involved.
1. Remove your sample from the scanner.
2.
Lower the cantilever holder:
• Rotate the ‘Engage Control Knob’ on
Cypher counter-clockwise to lower the
tip to a close distance ~1mm) above the
top of the scanner. This will allow easy
access to the top of the head assembly
where the light tube is located.
Note Although it is not required, for safety
reasons we recommend making motor moves
with the door closed. Beware of pinch points
(
Figure 20.1 on page 230).
3. Turn the ARC2 controller power off. This will shut off most of the Cypher’s power. It is not
necessary to disconnect the motor power supply when exchanging the light tube assembly.
